What is SmartOS?
SmartOS is an open-source, lightweight operating system designed for virtualization and containerization. It is built on top of the Illumos kernel, which is a fork of the OpenSolaris kernel. SmartOS is optimized for running multiple operating systems and applications simultaneously, making it an ideal choice for cloud computing, virtual private servers, and container-based deployments.
Main Features
SmartOS offers several key features that make it an attractive option for virtualization and containerization, including:
- Deduplication: SmartOS includes built-in deduplication capabilities, which eliminate duplicate data blocks and reduce storage requirements.
- Cluster repositories: SmartOS allows for the creation of cluster repositories, which enable multiple nodes to share a common repository of images and templates.
- Immutable storage: SmartOS provides immutable storage, which ensures that data cannot be modified or deleted once it is written.
